FYI - I have cross-checked all the v18 patch code against the v18 code
coverage [1] resulting from running the tests.
The purpose of this study was to identify where there may be any gaps
in the testing of this patch - e.g is there some v18 code not
currently getting executed by the tests?
I found almost all of the normal (not error) code paths are getting executed.
For details please see attached the study results. (MS Excel file)
